Roller rocker lash- too loose?
I hope someone can answer this or help. I am building a motor and getting ready to degree the cam- BBF V-8-- the pushrods I have come up with are 8.8" long, using EDL-60679 alum. heads, .048 compressed thickness head gasket and a set of FMS roller rockers. When I set 0 lash + 1/2 turn, the roller tip is of course in contact with the valve tip- My concern is the rockers "side to side" movement, when valve is not being depressed. It seems loose to me- hydraulic lifters/ cam by the way. Cam is Comp Cams 34-250-4. Will the movement go away after engine is fired up and the lifters pump up? PICTURE OF VALVE TIP is in 429-460 FMS Roller Rocker thread. (Showing center pattern) I just recieved the Trick Flow pushrods today, and am hesitant on going any further until i'm sure it's right. Thank you in advance.
